2x-3=12-2x+7x
Use the distributive property to multiply 2 by 6-x.
2x-3=12+5x
Combine -2x and 7x to get 5x.
2x-3-5x=12
Subtract 5x from both sides.
-3x-3=12
Combine 2x and -5x to get -3x.
-3x=12+3
Add 3 to both sides.
-3x=15
Add 12 and 3 to get 15.
x=\frac{15}{-3}
Divide both sides by -3.
x=-5
Divide 15 by -3 to get -5.
